sorear good * #perl6 01:20
TimToady: consider grammar A { multi method foo() { ... }; multi regex foo() { <...> } } 01:21
TimToady: A.foo is clearly a dispatcher - is it a LTM dispatcher or a nominal type dispatcher?
TimToady I suspect that normal methods won't participate in LTM unless they know the secret handshake 01:25
sorear phenny: tell masak STD.pm6 uses ~= to construct error messages in a few places. I haven't figured out how to make a sane (fast!) implementation of my $x; $x ~= "x"; ok $x eq "x"; 01:28
phenny sorear: I'll pass that on when masak is around.
sorear cpk++ # "Mo" is the best new unit I've heard this year. 01:29
no more "butbut 9 bit bytes" for me!
phenny: tell cpk I have a vague suspicion that on Windows Niecza isn't recognizing "\x0A" ~~ /\v/, and so rcrpg.pl is being interpreted as on one line, with the resulting right brace issues 01:30
phenny sorear: I'll pass that on when cpk is around.
sorear phenny: tell cpk [300 Mo Win64, 30 Mo Win32] Are both of those measurements for the second run? Sounds like more confusion from the "setting autocompilation on first run" wart. 01:31
phenny sorear: I'll pass that on when cpk is around.
TimToady decommuting & 01:32
sorear hey, I'm in a sane position to add -n and -p (correctly) now 01:34
I'm still hashing out the best factoring for implementing MY:: et al
jnthn: it's nqpnet:, and it's broken
TimToady: is $foo failover to package scope dependant on strict? 01:37
arnsholt sorear: Octets instead of bytes seem to be the normal state of affairs in Romance languages, if you care =) 01:54
01:59 [particle]1 joined
sorear TimToady: Is that definition of A erroneous? 02:00
TimToady maybe, and maybe... 02:05
PerlJam doesn't quite grok "multi regex"
02:05 noganex joined
PerlJam seems like that's the same thing as category matching but spelt different 02:06
sorear niecza: grammar A { proto regex TOP {*}; multi regex TOP:a { a }; multi regex TOP:b { b } }; say ?(A.parse("b"))
p6eval niecza v3-65-g55abf9d: OUTPUT«Bool::True␤»
sorear Right now, the proto is mandatory
I'd like to get rid of that while I unify multi-regex with multi-method 02:07
TimToady: What would you think of increasing the precedence of adverbs? 02:11
TimToady: currently if test1() && %hash<key>:exists { ... } has a parse that I find suprising
TimToady then use 'and' instead 02:12
has to be looser than =
sorear why?
TimToady $deleted = %foo<bar>:delete
sorear HAH!
in that expression, :delete binds to =, not <> 02:13
adverb precedence suprises even TimToady :>
er, actually, no 02:14
adverbs bind *just* tighter than =
if they were any looser, $deleted = %foo<bar>:delete would misparse
tightening adverbs, possibly as high as y=, wouldn't change that parse 02:15
niecza: my %hash = foo => 2; my $a = ""; say $a ~ %hash<foo>:delete;
p6eval niecza v3-65-g55abf9d: OUTPUT«Unhandled exception: Excess arguments to CORE infix:<~>, unused named delete␤ at /home/p6eval/niecza/lib/CORE.setting line 0 (CORE infix:<~> @ 0)␤ at /tmp/YsvPiFrVIG line 1 (MAIN mainline @ 5)␤ at /home/p6eval/niecza/lib/CORE.setting line 1261 (CORE C524_ANON @ 2)␤
..at /home/p6e…
TimToady adverbs used to be tighter, and that causes problems too 02:16
sorear we used to have many infix operators that needed adverbs 02:17
1..10 :by(5) parses correctly now, but wouldn't with y= adverbs
ditto 2 + 2 == 4 :ok("not in 1984") 02:18
TimToady tests was the other reason to make them pretty loose
(but tighter than ,)
sorear are there any plans to resurrect :ok? 02:19
PerlJam It's still in S03
TimToady yeah, but it keeps bouncing :)
02:20 whiteknight left
PerlJam that's not the kind of trampoline we need :) 02:21
I suspect that since the precedence rules are so inscrutable, people will use parentheses more often than not just to get the semantics right. 02:23
(for adverbs I mean) 02:24
at least for operators
maybe what's one thing should really be two things, one with a new syntactic marker :) 02:25
sorear adverbs have been looser than most infix operators for as long as the specs have been in mu
sorear would like a more complete specs repo, one with history going back to the first drafts of each document 02:26
Were the apocalypses "alive" and then "frozen", or did they have their present form for as long as they have been public?
do they have useful history?
PerlJam sorear: that apocalyses were "alive" at least until the synopses came into being. 02:27
sorear PerlJam: it's already easy enough to say (%foo<bar>:delete) with the present syntax, or ($x +< 1):rotate with tightened adverbs
PerlJam: I am merely arguing for a different Huffman code

Languages should supply their meta-objects that implement OO as they view it.
14:42 woosley joined
jnthn Parrot could contain the core 14:42
That's really up to Parrot folks :)
The core is pretty minimal. Doesn't even know what inheritance is, for exmaple.
mberends of course not Perl6, but you bothe probably mean Rakudo instead 14:43
the closer the parts align, the less glue we need to put on because of impedance mismatches 14:45
jnthn oh heh, I read "Rakudo" jsut because that's what I expected the question to say :)
Util mberends: yes, I meant "Rakudo" instead of Perl 6. Thanks 14:49
jnthn: which of the three will actually use MOP first? 14:51
twinshadow How can I makes calls to Parrot from Rakudo or another Perl 6? Would it just be NativeCall?
jnthn You can only make calls to Parrot from a Perl 6 implementation running on Parrot. :) But Rakudo is one that is. You can use pir::foo() to call Parrot opcode foo. Or Q:PIR { ... } lets you embed PIR. But you're making your code backend specific by using those. 14:53
NativeCall is for calling C libraries.
Tene twinshadow: at one time, Rakudo supported "use Foo :from<parrot>;", but that's been broken for quite a while afaik. 14:54
Same with eval "...", :lang<parrot>;
donri pir::, are those only in nqp?
rakudo: pir::say("hi"); 14:55

jnthn donri: In the not too distant future they'll need a pragma to make them work. 14:55
donri how does perl6 pragmas look?
jnthn So people declare up front they're writing a superset of Perl 6.
donri use pir;?
twinshadow Fun. I found a Markdown PIR, and was considering using it in a P6 Text-Markdown module
jnthn use ParrotyStuff;
or something

Tene donri: :lang
oh, wait, target? No. 14:58
donri Tene: say i want to eval ruby to a past in perl6
Tene It certainly could.
when I've wanted to do that myself, I've just grabbed the compiler object and called the methods directly
jnthn That's probably the better way.
donri or maybe there could be a compile() function :) 14:59
mberends does the TGIF dance and dashes to the de-commute &
14:59 mberends left
donri python does that: you can compile() to a code object that can then be eval()d or exec'd, useful if you're gonna eval the same thing more than once 15:01
15:01 Mowah joined
donri lucumr.pocoo.org/2011/2/1/exec-in-python/ 15:01
jnthn You can mimic that with Perl 6 eval just by evaling a closure :) 15:04
Though I agree that feels less neat.
15:04 shi left
donri which makes me wonder, is parrot (rakudo) compile-on-run or does/will it do anything like python's .pyc? 15:05
sure you can do that manually, compiling to .pbc
but if you just perl6 foo.pl twice, will it compile twice?
moritz_ I guess in the long run we'll do something like storing the .pbcs
15:06 gdey_ joined
moritz_ and I think there will be something like Perl6::Compiler.compile($string), which returns a Code object 15:06
which you can then invoke as $code.(@argv)
donri might be worth noting that python seems to have learned that storing them next to the source is suboptimal: www.python.org/dev/peps/pep-3147/
perhaps pbc's are supposed to be more backwards-compatible though, but then again, it's rather annoying to have pyc's all over your source tree 15:08
15:09 wtw left 15:13 nymacro left 15:19 woosley left, MayDaniel joined
flussence_ I think a good start would be $XDG_CACHE_DIR/parrot/${full_path_to_file}_${file_hash}.{pbc,pir} 15:20
jnthn You'll have to deal with rolling invalidations too. 15:21
flussence_ rolling invalidations?
jnthn gha, that was wrong wrod
*word
I mean
if you have a Foo.pm that is pre-compiled, and a Bar.pm that does use Foo; and then Foo.pm changes, then the cache of it *and* Bar.pm is now invalid. 15:22
It's all do-able, it just needs a bit more than file level :)
flussence_ oh, never thought of that. files that modify their caller's code...
jnthn It doesn't even need to be that complicated a case 15:23
If we compile calls to methods with v-table index optimizations, for example, and then the object changes, the indexes in the call are now invalid. 15:24
Or if the compiler decided to inline something from another module.
[Coke] jnthn: my vote is to just make compilation faster. ;)
15:24 hercynium joined
jnthn :) 15:25
My vote is for both :P

donri flussence_: the point in python though is incompatible bytecode between versions; if that could be an issue in parrot the path should be versioned too 15:50
also i don't see the point in filepath AND hash, just hash should be nuff? 15:51
or path + syncronised mtime
Tene flussence_: there are some patches submitted on trac that I wasn't able to verify correctness of; You could always take up the work yourself and try looking into the current state of this bug: trac.parrot.org/parrot/ticket/757 15:52
I would be shocked if the patches applied cleanly, but they might at least be relevant information.
flussence_ donri: if it has the filepath then it's easier to clean stale entries out, because there's a pointer back to the source file
donri true, but then it's also fixed to a filepath and dead if you move the source, not that it might be a big issue 15:53
flussence_ well, it's only a cache after all 15:54

takadonet what is the different between BEGIN {} and INIT {} ?
jnthn :/
colomon TimToady: and since it looks like it doesn't actually work yet... ;)
TimToady BEGIN runs immediately upon parsing 18:46
INIT runs at INIT time when the official run-time is starting up
so if you have separate compilation, BEGIN happens at compile, INIT at run
CHECK happens at the end of compile time 18:47
takadonet so if i wanted to initialize a package variable, it be better to set in INIT?
TimToady END at the end of run time
rokoteko I was mainly talking about the spec. isnt it true that stuff like $!.pending does exist? 18:48
TimToady the initializer on an 'our' is defined to run at INIT time
rokoteko but how does the pending queue end up in $! ? that is still a mystery to me.
TimToady there have been discussions of renaming $! to @!
rokoteko and what on earth is $! anyhow, is it an array, is it a variable?
TimToady: ahh.
I havent been following very closely. 18:49
TimToady several months ago now
rokoteko For several months I havent been following either. :)
Anyhow, Im happy to heard its proceeding. 18:50
TimToady and CATCH might actually be 'for @!' rather than 'given $!'

think about 'has'
assignment to 'my' is the least special 18:59

I assume Any() ?
TimToady I would assume so
jnthn That feels kinda weird. 19:00
TimToady yes, but we're trying to avoid Unicode operators
jnthn It's like making them init-time constants or something.

rokoteko "non-fast" mentioned at the develop phase?
diakopter where "fast" means "even fast enough to have a tolerable development/test cycle" 19:09
rokoteko where "mentioned at the develope phase" means "who gives a fucking shit?"
diakopter O 19:10
rokoteko Just make it work. when there are practical applications suffering from performance, then optimize it. :)
19:11 Lorn joined
TimToady one of the tenets of SSSDR is to do everything all at once, even though you can't... 19:11
rokoteko: and we are allowed to think about optimizability in general terms
diakopter :) all you want; my point was "development *is* a practical application"
(and if the development takes forever because the development/test cycle takes forever...) 19:12
rokoteko Ahh. Sorry, Im not a perl6 developer. Id rather see it fully working first and people use actually use it and *then* optimize for performance where you see the need for for it. but who am I to comment? 19:13
TimToady that's kinda either-or thinking, when the reality is we make a gradual transition from make-it-work to make-it-work-fast 19:14
moritz_ rokoteko: that was our approach at first too
rokoteko moritz_: what happened?
TimToady it was very slow
moritz_ rokoteko: and then we noticed that once we had a usable compiler (in terms of features), what people wanted next was speed
rokoteko Ahh.. Ive been critizing about that also.
moritz_ rokoteko: long before it was "done"
rokoteko "man, this is so slow, can this ever be done using Parrot" - I remember myself asking here. 19:15
TimToady the fact is that your optimize later approach works well with specific applications, but for interpreters and compilers you don't really know even when you're "done" where the user's hotspots are going to be
rokoteko: so now you're complaining that we're worrying about "faster"? :P 19:16
rokoteko ok. so $! (THE goddamn error variable) is not implemented yet. and then you talk about lazy evaluation but the feed operators arent yet working?
moritz_ rakudo: try { die "foo" }; say $!
p6eval rakudo a38d45: OUTPUT«foo␤»
rokoteko TimToady: yes, I understand the contradiction of my comments, but it's just my comments. :)
TimToady looks implemented to me
moritz_ who said it was NYI? 19:17
TimToady and feeds are only one form of laziness
rokoteko moritz_: arent they supposed to be stacked when using fail() ?
diakopter perl6: try { die "foo" }; say $!
jnthn rakudo: <foo bar baz> ==> map *.uc ==> say

moritz_ rokoteko: yes, but that's not the same as "not yet implemented"
rokoteko moritz_: oh. ok.
TimToady "working consensus and rough code" :) 19:18
rokoteko moritz_: so the stacking when using fail() is implemented?
moritz_ rokoteko: no
rokoteko ...
moritz_ rokoteko: it's not. But that doesn't meant that $! per se is not yet implemented
rokoteko Ok. who am I here to disagree.
Im just thanking you all for all the good work! :)
moritz_ there's a difference between "A doesn't exist" and "A isn't implemented in all details"
TimToady it's not the disagreement that's disagreeable, but the all-or-nothing bits 19:19
moritz_ TimToady++
TimToady we've been climbing the slippery slope for ten years now, so we're immune to half-empty/half-full arguments
rokoteko This has just been a real mental puzzle for me. To keep on appreciating perl5 and its modernization, to wait for perl6 and it's greatness, or to just check if Haskell really would suit me the best. 19:20
TimToady why do those have to be exclusive?!?! 19:21
moritz_ there's no need to wait, you can always speed up things yourself (hint, hint)
flussence_ that reminds me, I gotta go finish T-T-W today
TimToady all your arguments seem to be of the either/or variety
Perl has always been more about both/and. 19:22
dalek ast: d38ece7 | moritz++ | fudge:
[fudge] give a better error message for missing test files
 19:25
diakopter in my experience, deciding '[which language would] suit me the best' is often a euphemism for deciding 'which language would suit my employer's (and thus my) project the best, where I must take into account maintainability once I'm gone, and other concerns where multi-language knowledge/expertise *seem* to add costs'
takadonet flussence_++
diakopter (making it an either-or question) 19:26
so the frank answer to a complaint such as "This has just been a real mental puzzle for me." really ought to be "do *not* ever get your hopes up about Perl 6 unless you're willing to invest personally in it yourself, because there are precious few resources devoted/committed/invested in it (both historically and currently)." 19:29
sorear rokoteko: worrying about "fast" is specifically my prerogative. Rakudo can get away with being slow far more than "An implementation dedicated to exploring possibilities for efficient implementation"
diakopter: agree. 19:30

"sadistic Lojbanist" 20:15
sorear TimToady: if -p is passed, what should be used instead of CORE.setting? 20:16
colomon masak: classic lisp has some "wonderful" names. 20:17
sorear LAMBDA
rokoteko that raises a question. are rats more advanced than squirrels or the other way around? :)
sorear CDR
rokoteko anyhow Im going to visit a friend soon. and therefore Ill be thanking you all for the good chat :)
colomon CADR 20:18
rokoteko See you next time when I feel curious about perl6! :)
masak rokoteko: \o
sorear I think it's funny how lispies have latched on to lambda and car despite being approximately the worst names imaginable
plobsing sorear: what do you mean? cdaddaadr makes complete and total sense! 20:19
flussence_ lambda I'm sort of familiar with. "car"... no idea
masak Arc ditches 'lambda' for 'fun', but keeps 'car' et al for hystericacl raisins.
hysterical*
colomon yeah, I'm okay with lambda, which at least has mathematical meaning.
20:19 aindilis joined
masak (and with the rationale that it's hard to do 'caddr' et al with any other naming scheme) 20:19
sorear plobsing: once you know car and cdr, cdaddaadr is at least regular
diakopter preferred to read that as 'hysteric access-control-lists raisins' 20:20
masak sorear: though probably not the best of ideas in any event.
diakopter: *lol*
colomon If I'm understanding the wikipedia page correctly, cdaddaadr isn't actually supported (usually)
masak five levels of nested lists ought to be enough for anybody.
sorear Classical LISP has one of the most insane variable models every invented 20:21
plobsing colomon: I don't expect it to be. it was an extrapolation of a common pattern.
colomon ooo, wait, maybe it is. "Common Lisp and Scheme both provide forms with up to four repetitions of the a and d." might mean four each, I suppose.
masak ok, I've now updated strangelyconsistent.org/blog/p5-fin...-substring with small notices about colomon++ having the latest and best news on p5.
colomon: it doesn't, IIRC. 20:22
plobsing bringing the car/cdr discussion back on topic, would it be possible to augment the Perl 6 grammar to take any c[ad]+r function and autogenerate the appropriate accessor? 20:23
masak ...yes. :)
20:23 icwiener joined 20:24 thr0w left
masak plobsing: though my guess is that the autogeneration bit wouldn't end up in the grammar. 20:24
maybe in the actions, or maybe even later on.
jnthn Probably actions.
colomon masak: ah, good, you're planning on saying more on it. I think it's interesting (and nice) that the best algorithm depends on the sort of string you expect to be dealing with. 20:25
jdhore Does Perl (either P5 or P6) have something like radix tries?
shortcircuit I don't know what radix trees are, but suddenly I want them on Rosetta Code. >.> 20:26
jdhore en.wikipedia.org/wiki/Radix_trie
plobsing I've seen a Trie module on CPAN before 20:27
masak colomon: from what I see from your new stats, fox and moritz_ are both better off than I thought, but your algorithm beats them when strings get long.
jdhore I tend to call it a patricia trie, but radix trie is more accepted :(
masak jdhore: I haven't seen a radix trie implementation, no.
does STD contain anything like that? and is that part in Perl 6?
20:29 KyleHa left
sorear radix trees and patricia trees are not quite the same 20:35
masak: std used to use radix trees, but does no longer 20:36
masak oh!
colomon masak: that would be my summary as well. :) 20:40
masak I just like to have that summary spring out of data coming out of my runs :P no offense.
in retrospect, I made two mistakes with collecting statistics: 20:41
* data was a bit too one-sided, and favored certain solutions, skewing the results.
* the timings for each solution were all collected during one single program run. should have re-started the program each time. 20:42
sorear colomon: augment slang MAIN { token prefix:sym<cxxxr> { c <[ad]>+ r <O(|%named_unary)> } } should work
TimToady: when augmenting slangs, how do semantics get attached? Embedded blocks with &make? 20:43
colomon sorear++
sorear TimToady: what should I call the file that contains the -p setting? 20:45
sorear is mostly trying to get multis working, today. 20:46

%*LANG hash key
jnthn ah, ok
Is a slang meaningful in a non-augmentation sense? 20:48
sorear You could define an entirely new one 20:49
I'm not really happy with "slang" as a type_declarator 20:50
it feels more like a scope to me
augment slang \approx BEGIN { %*LANG<MAIN> but= role { ... } } 20:51
my slang \approx BEGIN { %*LANG<MAIN> = grammar { ... } }
supercede and my would be the same thing... I don't think any other scope makes sense 20:52

sorear so... I'm likely going to be working on a branch 21:48
masak sorear: that one's a workaround for a Rakudo thing.
sorear: would you be willing to work on a branch in the Yapsi repo?
prammer Would I be doomed to failure if I tried to implement some of the p6 builtin classes/roles in p5/Moose?
dukeleto sorear: yes, that was me 21:49
moritz_ prammer: depends on what you try
prammer Something like $hash->pairs->map( sub { ... } ); seems kinda nice
sorear masak: yes
masak sorear: excellent. you now have commit access.
dukeleto sorear: i think Perl 6 will be part of The Perl Foundation GSoC org this year
jnthn sorear: at_pos has to go? 21:50
prammer It seems like Parcel would be hard
dukeleto sorear: as well as Rakudo. But Rakudo-folk are free to be part of TPF or Parrot, as they see fit
masak sorear: my immediate plans include fixing the bug you pointed out (shouldn't be difficult), and then fixing the backtracking problems in the grammar.
sorear masak: how does "has FUTURE::Node @.children is rw" work? I thought Rakudo couldn't do typed arrays
masak prammer: what is your aim?
sorear: it parses them and then does nothing.
sorear: consider it a piece of documentation :) 21:51
21:51 hercynium left
moritz_ prammer: Parcel is very specific Perl 6 thing; I don't see how a Perl 5 program would benefit from it 21:51
sorear jnthn: masak's code uses at_pos, which is not standard Perl 6.
masak: ok. that I can do :)
prammer I think one of my aims it to figure out how all the p6 classes/roles fit together
masak prammer: if you find out, let us know :P 21:52
sorear masak: where does yapsi fail on rakudo, without at_pos?
prammer right. Well it could be a testing ground to see what works
sorear masak: have you ever thought about integrating yapsi with gge? :D
jnthn sorear: Oh, I thought it was spec.
moritz_ jnthn: pmichaud_ planned to spec it
jnthn Ah, OK
moritz_ but never got around to it
jnthn *nod* 21:53
masak sorear: yes, that was the plan when I had only GGE and hadn't started with Yapsi.
moritz_ there's some sense in it
masak sorear: oh, seems I'm mixing up at_pos with something else.
prammer I think I'd leave out Parcel, but I was hoping I could figure out Iterator but I'm having trouble
moritz_ postcircumfix:<[ ]> handles things like slices and WhateverCode closures etc.
masak sorear: anyway, I'd very much like to see an implementation-independent version of at_pos.
moritz_ and then calls at_pos for each index
so if you want to provide your own array-ish type, you only have to provide the actual storage calls 21:54
masak pmichaud_ seems quite proud over at_pos.
moritz_ for individual indexes
moritz_ likes it
same with at_key for hashes
jnthn Yeah, I like it too.
It made things a bunch simpler.
moritz_ sorear: are you OK with speccing at_pos? 21:55
sorear moritz_: possibly. 21:56
niecza's at_pos differs in some small details from what you just described
moritz_ sorear: care to elaborate? 21:57
sorear prammer: Iterator is in a state of flux atm. No major implementation follows the spec.
prammer: (the spec is lagging)
moritz_: my at_pos methods are responsible for handling WhateverCode and slices themselves 21:58
moritz_ sorear: so what's its advantage over postcircumfix:<[ ]> ? 21:59
sorear at_pos methods don't have to handle adverbs 22:00
prammer sorear: ah. good to know. I read some stuff about .reify but it still wasn't clear to me what the api is supposed to look like
sorear also, they're methods - postcircumfix:<[ ]> is a sub
moritz_ not at all
sorear: take a look at S13 22:02
prammer is there a good place to look to figure out the direction Iterable/Iterator are going? I guess I can look at how rakudo does it 22:03
sorear niecza chooses to follow S12:416 instead. 22:04
moritz_ sorear: S12:416 looks to me like an example of &foo(bar) and bar.&foo being the same. I don't see how that implies that postcircumfix:<[ ]> is a sub 22:08
